The recent turmoil in Myanmar has many Japanese companies on the alert for any signs of worsening prospects for what they see as a promising market.

The Myanmar military's seizure of power on Feb. 1 and subsequent civil unrest have cast a shadow over the Southeast Asian nation of 54 million people. An extended period of chaos may prompt Japanese firms to hold off on new investments and review their business strategies, experts say.

"We can say the coup is against democracy, but as one company what we can do for now is to keep close tabs (on what comes next)," an official at a Japanese company that does business in Myanmar said.
